If you can't tell by sight whether it is an actual painting or a reproduction, you're going to have to get someone to help you (a website can't do that, you need a real person). And you've given very little information for us to go on. "Board" could mean canvas board, cardboard, wood, lots of things. You haven't mentioned an artist, so I assume you only want to know about the medium.

Look at the surface of the piece very closely, with a magnifying glass if you have one. Do you see a regular pattern of tiny colored dots? Then it's a cheap photographic reproduction, and I've just saved you a trip to the appraiser.

On the other hand, if you see actual (not stamped) brush strokes and texture, it's probably a real painting of some kind. Its worth depends on the artist.

well u gotta make more sence.i mean real as in really oil paint or real as an original
